Biosurfactants “U-Champ” is made by microorganisms, it could be changes the fluid characteristics which are, viscosity and Interfacial tension (IFT). In this study, will be presented the effect of Biosurfactan “U-Champ” injection into the heavy oil sample on laboratory experiment. Viscosity and IFT measurement was carried out in this experiment to analyze the characteristic changes. Core flooding experiment also occur to measure the incremental of oil recovery. We used some of concentration of Bio usrfactant “U-Champ” (1%;2,5%;5%;10%). In this experiment, we found 5% concetration of Biosurfactant “U-Champ” as the CMC value. The result of observation indicates the reduction of viscosity from 5.57 cp to 1.76 cp at 30oC, and from 1 cp to 0.95 cp at 80oC, and reduced the IFT value from 10.05 mN/m to 3.81 mN/m. Based on the result, Core flooding experiment was occur to measure the incremental of oil recovery and obtained the increasing of recovery factor from 37,5% after waterflooding process to 81,25%. Finally, this studies feasible to continue in pilot project.
